Kungani umjikelezo wami wokuya esikhathini usuba mfushane? Ukuhlangabezana nokushintsha kwesigqi

Amaphethini okuya esikhathini angaveza okuningi mayelana nempilo nokuphila kahle jikelele. Uma umjikelezo ushintsha, kungavusa ukukhathazeka ngokuthi kwenzekani ngaphakathi emzimbeni. Abantu bavame ukuzibuza, kungani umjikelezo wokuya esikhathini ufushane? Nakuba abaningi belindele ukuthi ukuya esikhathini kufike ngezikhathi ezilindelekile—izinsuku ezingu-28 zingesinye isilinganiso esivame ukushiwo—ukwehluka kujwayelekile kakhulu, ikakhulukazi uma kuthonywa yiminyaka, ukucindezeleka, ukuguquguquka kwama-hormone, noma izifo ezingaphansi. Lesi sihloko sichaza izizathu ezingaba khona zokushintsha kobude bomjikelezo futhi sibheka ukuthi nini lapho lesi sikhathi esifushane singase sikhombise inkinga yezempilo. Phakathi nalengxoxo, sizohlola okutholwe kwakamuva ngokufinyezwa komjikelezo, sibhekisele ekulinganiseni kwama-hormone, izinguquko ngendlela yokuphila, kanye nokuhlolwa kwezokwelapha okungaba nendima. Ngokwethula imibono eminingana, lo mbono obanzi uhlose ukucacisa izici ezisemqoka ezingabangela ukuthi umuntu abone ngokuzumayo umjikelezo wokuya esikhathini ofinyeziwe.

Ukuqonda Izisekelo Zomjikelezo Ojwayelekile

Umjikelezo ojwayelekile wokuzala ungahluka phakathi kwezinsuku ezingu-21 kuya kwezi-35, kanti ukuya esikhathini kungathatha noma yikuphi kusukela ezinsukwini ezimbili kuya kweziyisikhombisa. Nakuba abaningi bebhekisela kumfanekiso oqanjiwe womjikelezo wezinsuku ezingu-28, iqiniso livame ukwehluka kakhulu. Ukusebenzisana kwama-hormone afana ne-estrogen ne-progesterone kulawula ukwakheka nokuchithwa kwengqimba yangaphakathi yesibeletho. Umjikelezo omfishane ungaba yizinsuku ezingu-21 noma ngaphansi, futhi kwezinye izimo ukushintsha kwesikhathi kuba sobala kakhulu. Ngokufanayo, uma uzibuza, kungani ukuya kwami esikhathini kule nyanga kuthathe isikhathi eside, kubalulekile ukubheka izinto ezifana nokushintsha kwama-hormone, ukucindezeleka, noma izifo ezingaphansi. Imikhiqizo efana ne-Conceive Plus Ukusekela Ukukhishwa Kwamaqanda ingasiza ukulinganisa ama-hormone futhi ithuthukise ukujwayeleka komjikelezo.

Ukuxhumana kwama-hormone phakathi kwe-hypothalamus yobuchopho, i-pituitary gland, nama-ovary kungaphazamiseka ngenxa yokucindezeleka noma izinguquko ekuphileni. Ezimeni ezinjalo, ngisho nomjikelezo ozinzile wezinsuku ezingu-28 ungashintsha—ungelulelwe ube izikhawu ezinde kakhulu noma ufingqwe ube, isibonelo, umjikelezo wezinsuku ezingu-23. Ukubona ngisho nezinguquko ezincane kungavusa imibuzo, okuhlanganisa ethi “kungani umjikelezo wami ushintshe usuka ezinsukwini ezingu-28 waya kwezi-35” noma okuphambene nalokho ethi, “ingabe ngihlangabezana nokufinyezwa komjikelezo wokuya esikhathini okufanele ngikunake?” [1]

Umehluko Wemvelo Nezigaba Zokuphila

Ubude nobuningi bokuya esikhathini kuvame ukuguquka phakathi nokuphila. Ebudodeni nasebusheni, imijikelezo ingaba ngeyongalingani ngenxa yokungakabi sezingeni kwemisebenzi yama-hormone. Kamuva, eminyakeni yokuzala, abaningi baba namaphethini azinzile kakhulu. Lapho kusondelwa kwisigaba se-perimenopause\—okuyisigaba sokudlula ngaphambi kwe-menopause\—amahomoni okuzala ashintsha kakhulu, okuholela ekuhambeni kokuya esikhathini okungajwayelekile noma okufushane. Lokhu kungaholela ekutheni ukuya esikhathini kube mfushane kunokuvamile noma izikhawu zisondele kakhulu, kwesinye isikhathi kubangele ukuya esikhathini kwezinsuku ezi-3 esikhundleni sobude obujwayelekile. Kuvame ukuba yilezi zigaba zokudlula lapho abantu beqala ukuqaphela ukuthi ukuya kwabo esikhathini kuya kufushane, okubenza bazibuze ukuthi “kungani ukuya kwami esikhathini kufushane” noma “kungani isikhathi sami sifushane kunokujwayelekile”.

Umthelela Wokucindezeleka Nezindlela Zokuphila

Ukwethuka okuqhubekayo, izinhlelo zansuku zonke ezimatasa, nezinguquko ezinkulu empilweni kungaphazamisa ukukhiqizwa kwama-hormone. Ihomoni lokucindezeleka emzimbeni, i-cortisol, lingacindezela imiyalezo evamile yokuzalana futhi lisheshe ushintsho emjikelezweni wanyanga zonke. Kwezinye izimo, lokho kungavela njengokuya esikhathini izinsuku ezimbili noma kuhambe usuku olulodwa kuphela, yize lezi zimo zingavamile. Izinhlelo zokuqeqesha umzimba ezinamandla kakhulu noma imikhawulo eqinile yokudla kwesinye isikhathi kuphazamisa ukuvuthwa kweqanda, kuholele ekutheni ukuya esikhathini kube mfushane noma kube nokugeleza okuncane. Kulawa macala, umuntu angase abe nokuhamba kokuya esikhathini okuhlala izinsuku ezi-2 kuphela azibuze ukuthi, “kungani ukuya kwami esikhathini kube izinsuku ezi-2 kuphela kule nyanga?” Impendulo ingase ihlotshaniswe ngqo nokucindezeleka noma ukuswela okuthile ekudleni. [2].

Izinguquko Ngokuzumayo: Ingabe Ukuthatha Izindlela Zokuvimbela Ukukhulelwa Kungaba Yimbangela?

Izindlela zokuvimbela ukukhulelwa ezisebenza ngamahomoni, okuhlanganisa amaphilisi, ama-patch, noma imijovo, zingahle zihloselwe ukunciphisa ukopha, okuholela ekutheni kube wukuhamba kwesikhathi kwezinsuku ezi-2 kuphela. Ngezinye izikhathi, indlela yokuvimbela ukukhulelwa ingakususela nhlobo ukuya esikhathini, ikakhulukazi izinhlelo eziqhubekayo eziklanyelwe ukunciphisa noma ukweqa izikhawu zokuya esikhathini. Uma usanda kushintshela endleleni entsha futhi uqaphele ukuthi umjikelezo wakho wanyanga zonke uya ufushane, amazinga amahomoni ale ndlela yokuvimbela ukukhulelwa angase abe yimbangela enkulu. Ngedivayisi efakwa esibelethweni (intrauterine devices)\—ikakhulukazi lezo ezikhipha amahomoni\—izinguquko zingaba ngokuzumayo, kuholele ekutheni ukuya esikhathini kube yizinsuku ezi-2 kuphela noma kube nokugeleza okuncane. Lo mkhuba ubangela ukuthi abanye abantu bakhathazeke ngokuthi “kungani ukuya kwami esikhathini kuhlale izinsuku ezi-2” kanti empeleni kungumphumela nje wokuthi umzimba ulungiselela amazinga amahomoni okwenziwa. [3].

Ukungalingani Kwamahomoni Nomsebenzi we-Thyroid

Ithambo lesitho samathumbu se-thyroid lilawula izinqubo zokugaya ukudla futhi lithinta ukuzalana. Kokubili i-hypothyroidism ne-hyperthyroidism zingadala amaphethini angajwayelekile, kuhlanganise nomjikelezo wokuya esikhathini omfishane. Umuntu ojwayele ukuhamba kokuya esikhathini okulinganisela kwezinsuku ezinhlanu angase azibone ngokuzumayo esekhulelwa izinsuku ezi-2, okumbangela imibuzo ethi “kungani isikhathi sami sesifushane?” noma “kungani ukuya kwami esikhathini kumile ngemva kosuku olulodwa?”. Izimpawu ezinjalo kwesinye isikhathi zikhomba ukuphazamiseka kwe-thyroid, okungathinta amazinga amahomoni okuzala. Udokotela angahlola ama-profayili e-hormone ukuze aqinisekise ukuthi izinkinga ezifana namahomoni e-thyroid adlulele ayayinikela yini ekufinyekeni komjikelezo wokuya esikhathini noma ekubeni nemijikelezo engajwayelekile ngokuphelele.

I-Perimenopause Nokudlulela Ku-Menopause

Ubude beminyaka yama-30 sekwephuzile kuya ekuqaleni kwama-50 buvame ukukhomba i-perimenopause, isigaba sokudlula esiholela ku-menopause. Ukuguquguquka okukhulu kwe-estrogen ne-progesterone kungaholela kumjikelezo wesikhathi okufushane izinyanga eziningana zilandelana. Abantu baqala ukubona izinguquko ezifana nomjikelezo we-day 23 noma ubude obufushane kakhulu, okungase kube uphawu lokushintsha kokuzala. Kuhambisana nezimpawu ezifana nokushisa umzimba (hot flashes), ukushintsha kwemizwa, nokuphazamiseka kokulala, lezi zinguquko zivusa imibuzo ephindaphindayo efana nokuthi “kungani isikhathi sami sime ngemuva kosuku olu-1 kuphela?” noma “kungani umjikelezo wami usuba mfushane?”. Nakuba kuyinto evamile, lezi zinguquko ezisheshayo zisengadala ukukhathazeka, futhi ukwelulekwa udokotela kungase kube kubalulekile ukuze ucaciselwe lokho ongakulindela ngalesi sikhathi sokudlula.

Ukuguquguquka Kwesisindo Nokungalingani Kokudla

Ukwanda kakhulu noma ukwehla kakhulu kwesisindo kungaguqula ukukhiqizwa kwama-hormone. Izicubu zamafutha omzimba (adipose tissue) zithinta amazinga e-estrogen, kanti izinguquko ezisheshayo zingaphazamisa i-hypothalamic-pituitary-ovarian axis elungisa umjikelezo wokuya esikhathini. Isibonelo, umuntu angase aqaphele ukuhamba kwegazi kosuku olulodwa kuphela noma ukuya esikhathini izinsuku ezingu-2 ngemuva kokuqala ukudla okudlayo okuqinile noma uhlelo lokuzivocavoca olunzima. Ngokufanayo, ukushoda kokudla okunomsoco—ikakhulukazi ama-micronutrients abalulekile—kungakhulisa ukuphazamiseka. Ngokuhamba kwesikhathi, ukungalingani okuqhubekayo kuholela emibuzweni enjengokuthi “kungani isikhathi sami sokuya esikhathini sifushane?” kanye nokuqaphela kakhulu ukuthi umjikelezo wami wokuya esikhathini uya ufushane.

Indima Ye-Genetics Kubude Bomjikelezo

Amaphethini okuya esikhathini angaba nelifa ngokwengxenye. Uma izihlobo zakho eziseduze ziye zaba nemijikelezo yanyanga zonke emfushane, engajwayelekile emlandweni wazo, kungenzeka ukuthi i-genetics idlala indima enkulu kumjikelezo wakho omfushane wokuya esikhathini. Lawa maphethini angavela kusenesikhathi, mhlawumbe okuholela ekutheni ngesikhathi sobusha ube nesikhathi sokuhlela izinsuku ezi-3 kuphela noma uqaphele ngokuzumayo umjikelezo wesikhathi okufushane usuwumdala. Nakuba amajini engasiqinisekisi isipiliyoni esifanayo, angakwenza kube khona ukuthambekela okuthile kwamahormone, okwandisa amathuba okuthi umjikelezo wakho wanyanga zonke ufushane ezikhathini ezithile zempilo.

Ukubaluleka Kwezinguquko Ku-Ovulation

Inani lamaqanda atholakalayo liyancipha njengoba umuntu eguga, futhi inqubo yokuvuthwa kwamaqanda (ovulation) ingase ingabe isaqondakali kalula. Eminyakeni eholela ku-menopause, ama-ovary angase asabele ngendlela ehlukile ezimpawini zama-hormone, kwesinye isikhathi esheshisa noma egxuma ngokuphelele inqubo ye-ovulation. Yonke le micimbi engajwayelekile ingahambisana nokuhlelwa kwesikhathi sokuya esikhathini okufushane. Ukuqapha i-ovulation—ngokwesibonelo, ngokusebenzisa amashadi okushisa komzimba okuyisisekelo noma ama-ovulation predictor kits—kungaveza ukuthi ukushintsha okusheshayo ngesikhathi sokukhishwa kweqanda kuhambisana nesiyingi esifushane. Ukuqaphela lobu budlelwano kusiza ukuchaza “kungani isikhathi sami sokuya esikhathini sifushane” uma usuqalile ukuphuthelwa i-ovulation noma uba nezikhathi ze-ovulation ezifinyeziwe. [4].

Umthelela Wengqondo Wemijikelezo Emfushane

Ukubona ukuya esikhathini okufishane kunokujwayelekile kungavusa ukukhathazeka ngokukhulelwa, impilo jikelele, noma inqubo yokuguga. Lo mjikelezo wokucindezeleka ungagcina uqhubekisela phambili ukungajwayelekile uma izinga le-cortisol likhuphuka, liphazamisa ama-hormone okuzala kakhulu. Ukudideka mayelana nombuzo othi “kungani ukuya kwami esikhathini sekuya kufushane” kujwayelekile, ikakhulukazi kubantu abahlose ukukhulelwa. Ukuphazamiseka ngokwengqondo kungakhula kube kukhulu uma lezi zinguquko ziqhubeka ezinyangeni eziningi. Ukugxila ekuzindleni, ekwelulekweni, noma ezinhlelweni zokwehlisa ingcindezi kungaseka uhlelo lwezinzwa, okungenzeka kunciphise ezinye izici yalemijikelezo emfushane.

Ukukhomba Nini Okufanele Ufunisise Udokotela

Kuyinkinga kwesinye isikhathi ukunquma ukuthi ingabe ushintsho olusheshayo esikhathini sokuhamba, njengokuthi ukuya esikhathini kosuku olulodwa noma ukuya esikhathini okuhlala izinsuku ezi-2 kuphela, kudinga yini ukuphenywa kochwepheshe. Ngokuvamile, uma lolo shintsho luqhubeka isikhathi esiningi izinyanga eziningana, kuhlakaniphile ukubona umhlinzeki wezempilo. Bangenza ukuhlolwa kwegazi ukukala izinga lama-hormone, baphumeze noma baphike ukungasebenzi kahle kwenhlokomo (thyroid), futhi bahlole nezinye izici zomzimba. Abaningi basebenzisa ne-ultrasound ukuze babone ukuthi ama-fibroid, ama-cyst, noma okunye ukungajwayelekile kungachaza ukuthi kungani ukuya esikhathini kwami kufushane kunokujwayelekile noma sekuqalile iphethini yokuba mfushane njalo yini.

Izici Zemvelo kanye Nama-Endocrine Disruptors

Ucwaningo olukhulayo lukhomba amakhemikhali atholakala epulasitikini, emikhiqizweni yokunakekelwa komzimba, ngisho nasemithombeni yokudla, angase asebenze njenge-endocrine disruptors. Nakuba izixhumanisi eziqondile ezidala inkinga zingahlali ziqinisekiswa, ochwepheshe basola ukuthi ezinye izakhi zingalingisa noma ziphazamise ama-hormone okuzala. Uma ukuvezwa kuphezulu, umuntu angase abone ukugwemeka okufana nokuba ukuya esikhathini kuhlale izinsuku ezi-2 kuphela noma ngisho ukugeleza okungajwayelekile kosuku olulodwa. Lesi sigaba sesayensi sisese kuthuthuka, kodwa ukukhulisa ulwazi kungasiza labo ababhekene nomjikelezo omfushane baxhumanise imikhondo ababecabanga ukuthi ayihlobene.

Ukubonisana Nochwepheshe

Ochwepheshe bezifo zabesifazane, ama-endocrinologist, nochwepheshe bokuzala ngamunye banombono oyingqayizivele lapho behlola umjikelezo wokuya esikhathini omfishane. Ukuhlolwa kwegazi kungaveza ukushoda kwama-micronutrient njenge-ayoni noma amavithamini B, okungasiza ukucacisa umbuzo othi “kungani ukuya kwami esikhathini kumile emva kosuku olulodwa?”. Ngasikhathi sinye, i-ultrasound noma i-MRI ingathola izinkinga zesakhiwo. Ubunzima bomzimba wesifazane kusho ukuthi ukuxilonga ukuya esikhathini okufishane kunokujwayelekile kungadinga ukuhlolwa okuningi. Uma ukuhlela umndeni kuyinto ebaluleke kakhulu, uchwepheshe wokukhulelwa angahlola kakhulu isikhathi sokuvela kweqanda ukuze aqinisekise ukuthi lo mjikelezo omfushane awuphazamisi imizamo yokukhulelwa.

Ngabe Imijikelezo Emifushane Ingase Ibe Nempilo Na?

Abantu abaningi imijikelezo yabo efushane bahlala benempilo ngokuphelele. Abanye baqhubeka nenqubo ejwayelekile ye-ovulation, kodwa umcamelo wesibeletho ushiyeka ngokushesha kunangaphambili, okuletha ukuya esikhathini kwezinsuku ezi-2. Umuntu angaba nokuhlangenwe nakho kwemvelo kokuya esikhathini izinsuku ezimbili impilo yakhe yonke. Uma kungekho ezinye izinkinga zempilo ezivelayo, ukuya esikhathini okufushane akusho ngokuzenzakalelayo inkinga. Nokho, ukuqapha kuhlala kubalulekile ngoba izinguquko eziphuthumayo—ezifana nokusuka ekuphumeni kwegazi izinsuku ezinhlanu uye ekuphumeni kosuku olulodwa—zingadinga uphenyo ukuze kukhishwe imbangela efihlekile noma ukuswela okungenzeka.

Ukusekelwa Ngokwengqondo Nemithombo Yomphakathi

Ukukhuluma ngomjikelezo wokuya esikhathini omfushane noma ukudideka ngombuzo othi “kungani umjikelezo wami usushintshe usuka ezinsukwini ezingama-28 waya kwezingama-35?” sekungasongelwa njengakuqala, futhi abaningi bathola induduzo ngokuxhumana nozakwabo ababhekene nezinguquko ezifanayo. Amaqembu okweseka aku-inthanethi nama-forum angaba izikhala zokwabelana ngolwazi, ezinikeza izincomo noma ukuzwelana. Nokho, ukuholwa nguchwepheshe kufanele kuhlale kuyisisekelo sanoma iyiphi inqumo ebalulekile yezempilo. Indaba yomngane noma yomuntu ongaziwa kungenzeka ingahambisani nesimo sakho somzimba esiyingqayizivele.

Imiphumela Ekuzaleni Uma Umjikelezo Ufushane

Izikhathi ezisondelene kakhulu zivame ukudala ukukhathazeka mayelana nekhono lokukhulelwa. Noma umjikelezo wokuya esikhathini ufushane ungabonisa ukuthi i-ovulation yenzeka ngaphambi kwesikhathi noma ayinandaba, abaningi basakhulelwa ngaphandle kobunzima. Uma usola izinkinga zokuzala, uchwepheshe angasebenzisa ukuhlolwa kwamahomoni ngezikhathi ezithile emjikelezweni. Lolu hlolo lungacacisa ukuthi ukuya esikhathini izinsuku ezi-2 kuphela lunomthelela yini kumcamelo wesibeletho noma kwekhwalithi yeqanda. Kwesinye isikhathi, iminyaka emikhulu kamama iqinisa lezi zinkathazo, kugcizelela ukuthi kungani ukubambisana nodokotela kubalulekile.

Ukuqaphela Amaphethini Okopha Kancane

Ukuphuma kokuya esikhathini usuku olulodwa kuphela noma amabala amancane kakhulu kungabonisa ukuthi umzimba awakhi umcamelo owanele we-endometrial. Izinga le-estrogen lingase lingabi nkulu ngokwanele, noma i-luteal phase ingase ibe mfushane kakhulu. Ngaphezu kwalokho, ukuphuma kwegazi kancane kakhulu kungase kubonise umjikelezo ongena-ovulation—lowo okhona kodwa isidoda esivela ku-ovary singakhululwa. Lezi zimo zingavusa umbuzo othi “kungani ukuya kwami esikhathini sekufushane?” noma “kungani ukuya kwami esikhathini kube izinsuku ezi-2 kuphela kule nyanga?” Amaphethini aphindaphindayo angaholela ekubhekeni ngokujulile impilo yamahomoni, ikakhulukazi kulabo abafuna ukugcina ukuzala okuqinile.

Ezinye Izizathu Zokuphela Ngokushesha Kokopha

Kwabanye abantu, ukuya esikhathini kwezinsuku ezingu-2 kuwufuzo nje. Kwabanye, izimo ezithile ezifana nokushwabana noma ukulinyazwa kwe-endometrium noma i-Asherman’s syndrome zinganciphisa izicubu ezitholakalayo, okubangela ukopha okuncane nokuphela masinyane. Labo abasanda kululama emisebenzini yokuhlinzwa noma ezinqubweni ezithinta ungqimba lwesibeletho bangabona umjikelezo wanyanga zonke ufushane emasontweni noma ezinyangeni ezilandelayo. Ama-antibiotic, izithasiselo zezitshalo, noma ezinye izidakamizwa ezibhalwe udokotela zingase futhi zinikele ekufushaneni okungalindelekile kwesikhathi sokuya esikhathini, nakuba ngokuvamile kube yisikhathi esifushane.  [5].

Isiphetho Esiyinhloko

Ekugcineni, ngokuhlola yonke le mikhakha engenhla, ungakwazi ukuqonda ukuthi kungani umjikelezo wokuya esikhathini ufushane futhi uthathe izinyathelo zangaphambili zokusekela impilo yakho yokuzala. Isikhathi esifinyetiwe—kungaba isikhathi sokuya esikhathini sezinsuku ezingu-3, ukuya esikhathini izinsuku ezingu-2, noma usuku olulodwa—singadida futhi sibangele ukukhathazeka. Izinto zendlela yokuphila, i-perimenopause, ukungalingani kwamahomoni, ukukhipha isisu ngamakhemikhali (birth control), ngisho nezinto zofuzo, yizimbalwa nje zezinto ezingaguqula indlela yokopha kwanyanga zonke. Ekugcineni, ukubonana nochwepheshe bezempilo ukuze uthole isiqondiso esihambisana nawe kungesona isinyathelo esingcono kakhulu uma njalo uqaphela umjikelezo omfishane noma uhlangabezana noshintsho olukhulu.
